Goodwin Hydroelectric Project

Stanislaus River, California

Project Profile & Applicant

FERC Project No. 13728 is undergoing Preliminary Permit Application (PPA) and early-Traditional Licensing (TLP) processes. The proposed 4.96 megawatt (MW) Project is to be located at Goodwin Dam on the Stanislaus River in Tuolumne and Calaveras counties, California. The Applicant is American Renewables (AR), DBA Goodwin Hydro, LLC (GH). Goodwin Dam is jointly owned (equally) by the Oakdale (OID), South San Joaquin (SSJID), and Stockton East Water irrigation districts (collectively, Districts). Goodwin Dam is about 1.6 miles downstream of Tullock Dam and about 9.9 miles below the U.S. Bureau of Reclamation’s (USBR) New Melones Dam. Goodwin Reservoir acts as an Afterbay to the Tullock/P-2067 FERC Project. The P-2067 Project is owned by The Tri-Dam Power Authority (OID & SSJID). The Goodwin/P-13728 proposed facilities are described below:

The proposed Project would utilize the existing District’s Goodwin Dam (101 feet-high) and Goodwin Reservoir. A Water Intake in the Reservoir would feed into a Siphon, that would bifurcate into four Pipeline/Penstocks, and feed into a Powerhouse sited at the base of the Dam. The Powerhouse would contain four 1.24 MW turbines that would discharge back into the Stanislaus River.

Federally Threatened - Listed Species/Species of Concern

There are no anadromous fish in the upper Stanislaus River (upstream of Goodwin Dam). However, above Tullock/P-2067’s dam lies the USBR’s New Melones Dam. A NMFS Biological Opinion on USBR contains a “Reasonable and Prudent Action” for fish passage of the distinct population segment of California Central Valley (CV) steelhead (Oncorhynchus mykiss) over USBR’s New Melones Dam and into “some suitable location in the upper Stanislaus River.” Thus, it is reasonably foreseeable that CV steelhead may be reintroduced into the upper Stanislaus River and into the vicinity of the Project.

FERC Relicensing Status

PPA/TLP processes are ongoing. GH filed a PPA in May 2010. NMFS provided comments in September 2010. FERC issued a Preliminary Permit in November 2010 for 36 months. GH filed a NOI/PAD and requested use of the TLP in October 2013. GH also filed a second PPA, upon the first Permit’s expiration, in November 2013. NMFS filed additional comments in January 2014. FERC issued the second Preliminary Permit and granted the use of the TLP in March 2014. FERC’s March 2014 Order specified that GH should hold a public meeting within 30-60 days and that comments on the PAD and study requests would be due 60-days after the public meeting. No further activity since March 2014.
